**Bengaluru, India (February 28, 2025)** – Therapeutic proteins, a rapidly expanding sector of the pharmaceutical industry, are revolutionizing healthcare. These biomolecules, derived from human proteins, treat a wide range of diseases, from infections to diabetes and cancer, by various mechanisms including replacing deficient proteins or inhibiting abnormal ones.

Unlike the small molecules that comprise 90% of current pharmaceuticals, therapeutic proteins offer advantages such as fewer side effects, higher potency, and longer circulation times. This field’s history spans over a century, starting with serum therapy for diphtheria in the 1890s and progressing through milestones like biosynthetic insulin in 1982 and the development of monoclonal antibodies.

Currently, the FDA has approved 894 therapeutic proteins, a market valued at $341.1 billion in 2023 and projected to exceed $600 billion by 2033. Strong patent protection and faster FDA approval times contribute to the financial attractiveness of this sector.

However, challenges remain. High development costs and long timelines, coupled with a relatively low approval success rate, are significant hurdles. Protein degradation during manufacturing and potential immunogenic responses also pose difficulties. Furthermore, current protein therapeutics struggle to target many disease-causing proteins, particularly those with unstructured regions.

Despite these obstacles, advancements in biotechnology, synthetic biology, and AI are paving the way for innovative solutions. Researchers are exploring alternative protein scaffolds, using AI for drug design, and developing novel therapies such as CAR-T cell therapies and multi-specific antibodies. The increasing demand for biosimilars and biobetters aims to improve global access and affordability. By addressing current limitations, researchers hope to unlock the full therapeutic potential of proteins and provide new treatments for debilitating conditions.
